38, male, 5'7, 170, body fat ~14.5%, exercise regularly (tennis 3x/week, cardio at gym for 45-50 min at 80-85% HR Max (aerobic zone) 2-3x/week, weightlifting 2x/week. Exercising since 21. Non-smoker, no drugs or history of, no meds, drink once/week & have since college. No medical probs. Family heart history: largely ok--both parents are fine & are still alive at age 75 w/no known probs.
BP: 120-140 over 70-85. Usually the diastolic is bordering high, systolic is usually around 70-72. Father's side has high BP history.
This all began when I had PVCs, which medics have convinced me are benign. I've had a few here & there ever since I first "felt them" at age 19 but in late 2009 they were frequent (100-200+/day). Stress was also high at this time-I'm sure there was a connection in. At any rate it prompted me to do full cardio evaluation at Kaiser. EKG was fine. Stress test fine (even good). I was told Echo was normal. I had 2 echo's done...2007 & Jan 2011. I've lost the results from the 2011 test but my cardio said it was normal. I DO have my 2007 results & I noticed a few things:
(1) bradycardia--typically resting HR is 49-53. I always thought this was due to exercise but now I'm not sure.
(2) Borderline low LV EF: 50%-55%.
(3) Mild mitral regurg. Dr's said it's minor & he can't even detect it via stethoscope most of the time.
In tennis matches I often get winded after the first few long rallies of the match. Oddly after as many as 2 or 3 hours later a long rally does not make me nearly as winded. I also notice that if I walk up to say the 3rd floor of a building it feels like work. I would think this would be a piece of cake for someone athletic. So is my heart not working efficiently? Could the bradycardia account for me feeling a bit more worked than I think I should after walking about a couple flights of steps? Perhaps my HR just needs to be higher & it won't feel as strenuous? My MAIN concern is: bradycardia & somewhat low LV EF.
